Which type of electromagnetic radiation must be observed using a space based telescope?
ultraviolet light
What type of electromagnetic waves do earth based telescopes collect?
Astronomers have a huge problem detecting radiation from space because the Earth’s atmosphere blocks most of it and stops it from reaching the surface. Visible light and radio waves get through to telescopes on the ground, and some detectors (infrared, UV and gamma) work when they are high up on mountains.
Which electromagnetic has the highest frequency?
Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies.
What are modern day telescopes made of?
The reflective coating for telescope mirrors is usually made from aluminum, and the protective coating on top of the reflective coating is usually composed of silicon dioxide. Hardware components that are directly involved with the optical system are usually manufactured from steel or steel and zinc alloys.
What is the difference between an ancient optical telescope and a modern one?
The first telescopes were obviously of inferior quality, and had simple lenses instead of doublets which reduce chromatic abberation. They also had a concave eyepiece (like opera glasses) which give an erect image, while modern telescopes usually have convex eyepieces and an inverted image.
Which telescope has the highest magnification?
The highest magnification of a telescope is 50x per inch of aperture.
Why have no large refracting telescopes been built since 1900?
Why have no large refracting telescopes been built since 1900? -Refracting telescopes suffer from chromatic aberration. -Making large glass lenses without interior defects is difficult. -Large glass lenses are more difficult to support than large mirrors.
Was Galileo from a poor family?
1. He was a college dropout. Galileo, whose father was a lute player and music theorist, was born in Pisa, Italy. Although his father was from a noble family, they weren’t wealthy.
What invention made Galileo wealthy?
Galileo invented many mechanical devices other than the pump, such as the hydrostatic balance. But perhaps his most famous invention was the telescope.
